More Information
Summary:The invention discloses a motor noise optimization method. The method comprises the steps of obtaining an initial resonance area of an initial motor and an initial end cover; manufacturing an improvedend cover according to the initial resonance area; repeating the steps to sequentially improve the end cover; installing the finally manufactured improved end cover on the initial motor to obtain animproved motor, and carrying out a whole vehicle test to obtain an improved resonance area of the whole vehicle and the improved motor; and continuously improving the improved end cover to obtain a re-improved end cover until the resonance band width of the resonance area of the whole vehicle and the motor is further reduced after the whole vehicle is tested. According to the method, the motor endcover mode is analyzed, so that the end cover structure is optimized in a targeted manner, the optimization effect on the overall noise of the driving motor is obvious, the mode analysis time is short, the mode analysis result
